@@luckygen1001 Hello how are you doing This bus my first time to watch such a good video. My name is simba temani from Zambia city Lusaka. Can this furnace of your smelt chrome ore
Thanks for great video. I had problems with cracking as the mould cooled on some model loco spoked wheels. I had recycled some cast iron and now thinking it might of had contaminants that had made it too brittle and crack rather than heat stress shrinkage cause the cracks. Had thought about adding steel to give a little bit of ductility but never did. Going to try again after watching you. Did not realise just how much black magic there was in getting the blend just right,so many different combinations of alloys in the iron!
Great demonstration as always👏, I've often wondered how to add steel into the melt and not lose it's properties. I'm wondering if I'm adding enough Ferro silicon to my melts after seeing this though.
Thanks heaps for the vids. After doing a poor job of trying to cast iron last weekend I was able to do so successfully today. Using your videos as a reference I discovered that I was adding far too much air and it was cooling things off and creating slag. Today there was next to no slag and poured super fluidly
Fantastic, wow and that machine finish is awesome. I am really enjoying your video's sir. You are so down to earth and full of practical information obviously the lessions of years of having a crack, experimenting with metals.....needless to say failures along the way but we the viewers are the recipients of your excellence. Just great, sucj a pleasure and what a great learning tool your videos are. Heading off to hospital next week for a knee replacement so part of the rehabilitation will be a healthy dose of catching up on your videos. Cheers
Looks great M8! Your methods are very sound. Thanx for a great pouring session! I'd like to have you pour a big skull for me, but the shipping would be detrimental to my finances! LOL
Hey Luckygen, do you have tips to recognize different types of steel by inspection? How can you tell the difference between construction steel and free-cutting steel? They look the same to me.
on the vise nut with the riser, would a radius at the riser/part transition have eliminated the hot spot, and resultant shrinkage hole in the part? your vids are not only incredibly educational, but also equally addictive, lol
luckygen1001 no argument on that point, especially as the shrinkage on the "no riser" part is basically a symetrical blemish that could easily be compensated for in the pattern design, while the risered part shrink hole seems more structurally significant. Facing a blemish off seems no more arduous than cutting a riser off, lol. I'm more curious of the "mechanics" of the hot spot formation than advocating risers, as a part/pattern profile could cause a similar "transition of planes" problem in a complex part. Your expertise is obvious, and a question never asked is an intelligent answer never heard. Thanks for providing one!
How long does it take new iron, steel, and additives to mix uniformly? It sounds like some of the process involves endothermic or exothermic chemical reactions.
Have you tried to create high-carbon steel by melting cast iron and then adding some low carbon steel or iron nails? I would be interested to cast some parts which require higher tensile strength than normal cast iron, but still could be melted in a normal furnace. I guess when the carbon content gets too low, the melting point rises too much for this kind of furnace.
No I have not tried to create high carbon steel by adding low carbon steel to cast iron. A long time ago I did an experiment to see how much steel I could add to cast iron, 5Kgs of iron was melted and then added 5 Kgs of steel and it worked. Cast iron has to be very hot to dissolve steel and you have use small pieces as large pieces take a long time to dissolve.
@@luckygen1001 Interesting. 5kg of steel added that's surprisingly much. The carbon must have gone below 3% or even below 2%. Would be interesting to know how much stronger this is than normal cast iron.
great vid Luckygen, I see your plinth stuck to your cruicible too. (i've only done one bronze melt and mine stuck too) should i be worried that it might fall off mid pour? cheers
There are hundreds of steels and they all have a different melting points. Pure iron melts at 1534 C. There are lots of challenges with steel castings and is out of my league.
Next time instead of coke try glas perls like used as blasting media, the glass melts before the steel or cast iron, it floats ontop and creates a protective layer like the slag on arc welding electrodes make on your welds You can either pour it off before casting, skim it with a spoon or cast with it and make the cast iron spout in a way that it collects the slag on the surface thats also the way blacksmiths smeltered the iron they needed in the middle ages, lletting coal powder and crushed iron ore reduce to iron under a protective glass layer, the created CO2 usually just floats through the glass and also can create a shielding effect in addition to the glass itself, you should try that
Hey, I've been reading about ferrosilicon. Apparently it's made with silica (quartz or sand) , Coke (or charcoal), and millscale (but sometimes out of scrap steel) I would love to see someone make ferrosilicon with sand, wood charcoal , and scrap steel!
Some of that coke does burn off but you need add enough to have a layer to protect the steel from burning. Just before I am ready to add ferrosilicon, coke and slag are removed. If I leave the coke it will run into the mold and block the flow of cast iron to the other parts of the mold cavity.
Ah, got it, that makes sense to me now. So the coke protects the iron beneath (from oxidation) by consuming any oxygen that makes its way in there and essentially covering the molten iron surface with a layer of carbon dioxide (not unlike certain welding operations), and then you remove that "coke cap" just before pouring, once its protection role is completed. And, along the way, it may provide some free carbon that's taken up by the iron. It sure does produce a beautiful casting. I don't think I've ever seen a cross-section that was so consistent! I learn at the feet of the master :)
I tried to melt broken brake discs in small pots, but I didn't manage to bring them to a liquid state even though the temperature was very high, it melted my oven, I don't understand why it didn't work, what's wrong?
Gday Lucky I would like to ask you 2 question around coke. Do you make your own coke? And if so how do you do it.? I've been reseaching it and 1 thing I'll read says 12-36 for it to melt don't let it burn and the next thing I read or watch is just baking off the impurities and you got coke once it stops smoking. Can you please help me with this one. Thanks Derek
@@luckygen1001 I was also wondering about other trace elements like sulfur or any other strange things that may have been added to the steel. Would it oxidize them to?
@@luckygen1001 Depends on what someone calls old ; } In China a 25 year old girl is considered over the hill. But one things for sure, none of us are getting any younger.
Could you not add oxygen to the air blast and achieve higher temperatures? Would the furnace and crucible withstand such temperatures, or would you have to use a cupola design?
I discovered the name of the alloy It is chromium cast iron But i don’t know what ratio of cast iron and chromium A foundry near to where i live he is mixing stainless steel 1kg miled steel 5 kg and 10 kg cast iron
Wow how many time to change liquid iron, please answer. next time try it with iron granules from tile and nails and engine bearings. I want to know the results
This channel is insanely informative. I am so happy I stumbled upon it!!! Thank you for such great work!!

@@simbatemani5404 Most likely not.
Thanks for sharing and explaining so well, and your responses to questions.
This was a great video, not only did you cast it, show your ratios, but also the tests, and machining of the final products!
Very impressed by the sound when facing in the lathe - sounds like very good cast iron.
Yes you are right it was a delight to machine!
Very pleasant to watch. Accurate work and narration. Hope to see many more videos.

You are right iron castings should not crack when cooling down maybe a contaminant in there.
Really big respect to you sir..i want to know more about metal features..casting and mixibg metals..keep going..respect

👍👍👍👍
Make more video 🔥🔥🔥😁
Great stuff Lucky. I wish I could import your knowledge into my brain. Keep the vids coming!
You need to have another try at melting cast iron.
You are correct, sir! I'll give it a try with my cheapo setup when I get a chance.
Thanks fo sharing
Cool video, I'm looking for steel casing. Can you do a video on making a cast using soup cans as the melt? Thanks and keep up the good work!!
Finally someone who knows what they are doing! Your castings look beautiful! Keep up the good work!
Have you seen olfoundryman channel? He knows what he is doing.
@@luckygen1001 that guy is on his own level.
Keep em coming, you've got my subscription.
Request, please do melts of fine metals and some good mixes for jewelry making.
Sorry I don't melt gold or silver.
Good job!!
Absolutely brilliant.
Such a good yt channel
You are a very brave man machining in a lathe with hose clamps holding the half's together. Keep up the great work pouring metal !!!!
Hose clamps are a very effective way to clamp the two halves together to machine them.
very nice sir
thanks for sharing
Brilliant!
Hi, ever tried melting milling chips/shavings or grinding dust ?
Looks great M8!
Your methods are very sound.
Thanx for a great pouring session!
I'd like to have you pour a big skull for me, but the shipping would be detrimental to my finances! LOL
Casting a skull would require a lot of cores to make it work. Yes you are right shipping to the USA is expensive!
I'm trying to learn more about cores.
That's part of why I watch your vids! :D
Thanx again!
I have a lot of videos about cores.
Wow, good job
nice show
very nice work
thanks for sharing.

Alhamdulillah good info :)
excellent and very practical.
Where did you get the metal flask?
Good jovem , I AM from Brazil
Cruciable risers made from?mine is too low also
very good sir!

Which material is used for melting cast iron?
Backyard iron casting. I dip my hat to you sir. Impressive.
How long does it take new iron, steel, and additives to mix uniformly? It sounds like some of the process involves endothermic or exothermic chemical reactions.
Adding ferrosilicon causes a exothermic reaction. Iron and steel don't take long to mix uniformly.

Why not use flux for melting screws?
Hey, I've been reading about ferrosilicon. Apparently it's made with silica (quartz or sand) , Coke (or charcoal), and millscale (but sometimes out of scrap steel) I would love to see someone make ferrosilicon with sand, wood charcoal , and scrap steel!
Beautiful melt! What happens to the coke? Do you just wait for it to burn off or do you just remove the excess with the slag before pouring?
Some of that coke does burn off but you need add enough to have a layer to protect the steel from burning. Just before I am ready to add ferrosilicon, coke and slag are removed. If I leave the coke it will run into the mold and block the flow of cast iron to the other parts of the mold cavity.

ONE word. Magic!
How much propane did this use?
OR just whatever fuel you used
10 liters of waste oil.

Just think of the possibilities of recycling if you had one.

I don't make my coke it is a lot easier to buy it.
@@luckygen1001 Gday thanks for your reply mate I'm starting to think thats the best option for now. Thanks again for your help I appreciate it. Derek.
For doing this job is better waste oil or diesel for the maximum heat?
If you have plenty of money use diesel or if you are poor like me use waste oil. Both will generate high temperatures to melt cast iron.
luckygen1001 Thank you so much.You are not poor,you are amazing
what crucibles do you use?
Clay graphite.
Exelente trabajo
Con este horno UD puede hacer llaves de herramientas?
What kind if furnace is that i thught you can only melt steel with arc furnace.
Waste oil burning furnace.
Is that cooking oil you use or motor oil?
Motor oil.
If you oxygenate the steel, will it purify the steel into back into raw iron? If not, do you know how one could go about doing this?
Blowing oxygen through steel will burn all the carbon and it will be pure iron.
@@luckygen1001 I was also wondering about other trace elements like sulfur or any other strange things that may have been added to the steel. Would it oxidize them to?
Oxygen will oxidize most other elements because of the high temperatures.
is rebar a good candidate for recycling?
I have never used rebar but you could try it and tell me how it went.
What kind of furnace is this?
Waste oil burning furnace.

ever make a damascus can with screws makes a nice pattern
thank you but how we can increase the hardness of steel when we melt it ?
Cooling steel rapidly will increase hardness or you can add hardeners like chromium.
You say casting steel is "out of your league". Could you elaborate some? BTW. . . Great video.
My furnace will not reach steel pouring temperatures.
Could you not add oxygen to the air blast and achieve higher temperatures? Would the furnace and crucible withstand such temperatures, or would you have to use a cupola design?
Furnace and crucible would not stand up to those temperatures.
A cupola is the perfect carburisering furnace for steel.
Can you melt stainless?
No.
Gre@t!
10% thats why is it usually forge-welded together becaqse it oesn't mix well.
using wood in a refractory for preheat.
